[IDCS2 JS] Adding Page References to Topics Within A Book

Hi,

I'm using CS2 JS, and I'm trying to add page references to my index topics.

Here is my code:

var myDoc = app.activeDocument;
var myStory = myDoc.textFrames.item("IndexStory").parentStory;
var index = myStory.associatedXMLElements;

if (myDoc.indexes.length == 0) {
myDoc.indexes.add();
}

for (var i=0; i<index.xmlElements.length;i++) {
var category = index.xmlElements[i];
for (var j=0; j<category.xmlElements.length; j++) {
var element = category.xmlElements[j];
var topicLvl_1;
if (element.markupTag.name == "ati:category.head") {
myDoc.indexes[0].topics.add(element.contents, i.toString());
topicLvl_1 = myDoc.indexes[0].topics[i];
} else {
topicLvl_1.topics.add(element.contents);
markCompany(i, element.contents);
}
}
}

myDoc.indexes[0].update();

function markCompany(sector, companyName) {
app.findPreferences = null;
app.changePreferences = null;

var results = app.search(companyName, true, true, undefined);
for (var i=results.length - 1; i > -1; i--) {
if (results[i].parentTextFrames.length > 0 &&
results[i].parentTextFrames[0].parent.appliedMaster != null &&
(results[i].appliedParagraphStyle.name == "Company Name" ||
results[i].appliedParagraphStyle.name == "Company Headline left just." ||
results[i].appliedParagraphStyle.name == "Company Headline right just.")) {
test = myDoc.indexes[0].topics[sector];
test2 = test.topics.item(companyName);
//InDesign Restarts here
test2.pageReferences.add(results[i], PageReferenceType.currentPage);
}
}
}

on the line after the comment, when ESTK executes that line, InDesign crashes. I'm using a OS X Tiger.

Is this has something to do with the scope of my search? cause when i'm only searching the active document, this does not happen. But I have to search all documents that belong to the book.

Thanks,
Jeff
